Job description

Overview

Location: Huntsville, AL. Relocation assistance is not provided. Secret DoD clearance is required to start. This Sr Principal Software Engineer (Algorithm) – TRK (26-332) role supports the C2BMC program within Northrop Grumman Space Systems—Missile Defense Integration.

The position involves designing, developing, integrating, and leading Java-based mathematical algorithms for SLD (Discrimination/Tracking) to support C2BMC operational capabilities. The candidate will work with multi-disciplinary teams to ensure mission success and alignment with operational requirements.

Responsibilities

• Lead the design and development of complex, Java-based mathematical algorithms for SLD, focusing on tracking and discrimination to support C2BMC capabilities.
• Develop and maintain algorithm-design artifacts, including architecture descriptions, design documentation, and technical presentations.
• Implement MATLAB and/or Java-based software changes and prototypes, and support the transition of prototype algorithms to real-time tactical Java implementations.
• Support or lead design and code reviews to ensure high-quality, maintainable, and testable software solutions.
• Perform software testing, data analysis, and troubleshooting; identify root causes of system behavior issues and recommend effective solutions.
• Support integration, testing, and verification of algorithm design and performance across lab, ground test, and flight test environments.
• Present developed designs, analyses, and results to internal and external stakeholders, including program leadership and customer representatives.
• Collaborate with Systems Engineering, Integration and Test, Deployment, and Warfighter Support teams to ensure mission success and alignment with requirements.
• Actively participate in agile planning and execution using established C2BMC processes, including backlog refinement and sprint ceremonies.
• Mentor junior engineers and contribute to continuous improvement of RA ART processes, tools, and technical approaches.

Basic Qualifications

• A current, active DoD-issued Secret security clearance is required to start.
• Bachelor’s Degree in Computer Science, Software Engineering, Mathematics, Physics, or related field with 8 years of experience; or Master’s degree with 6 years of experience; or 12 years of relevant experience may be considered as an alternative to a degree.
• 7+ years of experience designing and developing complex mathematical algorithms related to data fusion, transferability, signal processing, sensor discrimination/classification, or Kalman filtering.
• Proficiency in full lifecycle development, algorithm creation, data fusion, and software implementation of mathematical algorithms.
• Strong data analysis, technical writing, agile methodologies, and problem-solving skills.
• Experience with MATLAB, Python, DevSecOps, systems integration, Unix/Linux, and radar signal processing.
• Experience in analysis, testing, and verification of algorithm design and performance; experience transitioning prototypes to real-time tactical implementations.
• Good verbal and written communication skills and the ability to work independently in a dynamic environment; ability to work with multiple teams (Systems Engineering, Integration and Test, Deployment, Warfighter Support).

Preferred Qualifications

• Active DoD 8140 certification at IAT Level II or higher (e.g., Security+ CE, CCNA-Security, CySA+, CND) is highly preferred; candidate to maintain certification throughout the contract.
• Experience with missile defense sensor discrimination and full lifecycle development of complex mathematical algorithms (data fusion, tracking, correlation, guidance, BMDS radar management).
• Experience with agile development, sprint planning, DevSecOps, and Java-based applications on Unix/Linux.
• Experience with Git/GitLab, Eclipse, Maven/Gradle, SonarQube; developing automated unit tests and verifying requirements.
• Experience reviewing system engineering artifacts (ICDs, use cases, sequence diagrams) and presenting design/test results to customers.
• Experience with MATLAB or Python-based algorithms prior to adoption into tactical Java software.
• Experience in the BMDS domain and command-and-control system application development is a plus.
